TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that results are paginated one page at a time, but says nothing about page size, result volume, auth requirements, or rate limits, so it only modestly exceeds the structured data.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, no filler. The core purpose and pagination constraint are front-loaded, and the routing hint follows immediately after.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be described, and annotations cover the read-only, open-world nature of the call. The one rough edge is that the description calls filtering 'optional' while all 13 parameters are marked required in the schema; a short note on which inputs can be omitted would close the gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with every filter's allowed values enumerated in the schema itself, so the baseline of 3 applies. The description's mention of filtering and sorting across 'games, add-ons, and subscriptions' adds no syntax or format detail beyond what the schema already documents.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives a specific verb and resource ('Fetch one cursor-paginated page of Xbox catalog items') plus scope ('optionally filtered or sorted across games, add-ons, and subscriptions'). It explicitly distinguishes itself from two siblings, xbox_search and xbox_collection, so an agent can route without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It names the two alternatives and the condition that selects each ('xbox_search for text lookup', 'xbox_collection for a curated grouping'), which is strong routing guidance. It stops short of an explicit 'use this when' statement (e.g. open-ended catalog exploration with no query), which is left to inference from the exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
